Data Questionable Power Event Register
The Data Questionable Power Event Register latches transition events from the condition
register as specified by the transition filters. Event registers are destructive read-only.
Reading data from an event register clears the content of that register.
Data Questionable Power Event Enable Register
The Data Questionable Power Event Enable Register lets you choose which bits in the Data
Questionable Power Event Register set the summary bit (bit 3 of the Data Questionable
Condition Register) to 1.
Query: STATus:QUEStionable:POWer[:EVENt]?
Command:
STATus:QUEStionable:POWer:ENABle <value> command where <value> is the
sum of the decimal values of the bits you want to enable
Example: Enable bit 9 and bit 3 so that whenever either of those bits is set to 1, the Data
Questionable Power summary bit of the Data Questionable Condition Register is
set to 1. Send the command STAT:QUES:POW:ENAB 520 (512 + 8).
Query: STATus:QUEStionable:POWer:ENABle?
Response: Decimal value of the sum of the bits previously enabled with the
STATus:QUEStionable:POWer:ENABle <value> command.
